    If 2 pounds of force is applied to the handle end of a 5-inch wrench, how much torque has been developed at the bolt end of the wrench?

    • 2½-inch-pounds

    • 5-inch-pounds

    • 10-inch-pounds

    • 20-inch-pounds

    Correct Answer
    A. 10-inch-pounds
    Explanation
    Torque is calculated by multiplying the force applied to an object by the distance from the point of rotation. In this case, a force of 2 pounds is applied to the handle end of a 5-inch wrench. To calculate the torque at the bolt end, we need to consider the distance from the point of rotation. Since the wrench is 5 inches long, the torque is calculated as 2 pounds multiplied by 5 inches, which equals 10 inch-pounds.
